I found this article could be interesting for Fans. http://members.tripod.com/stickgrappler/wck/wslbl.html Here's a only a piece of the Article - At once I turned my left punch into a protecting hand and used my right hand to pierce towards his throat. Although we did not use much of our force, we both were hit. He jumped away, and said, "Leung, actually I hit you first. Do you think so?" I smiled and answered, "Don't take it seriously. Who first hit the other is not the most important thing. It is the strength of the hit that matters. You are right. Your hand hit first, but my protecting hand had already dissolved much of your power. Truly, if you strike with all your force, I may not be able to stand it, but if the power is greatly reduced, the strike will not be so effective. On the other hand, my hand also grasped your throat. If we had really fought, surely you would know who would have been hurt more badly."
